Community involvement – by people and insects – at Calera Creek

April 20, 2012 | Stanford University

Making our way through the dense willow thickets surrounding Calera Creek in Pacifica, CA, our group of eager ReNUWIt researchers, warmly self-dubbed the Stream Team, watched as the late season rain’s runoff and the local water recycling plant’s effluent slithered together through the creek towards the ocean. It didn’t take long for Janet Hsiao, an ambitious UC Berkeley undergraduate student and ReNUWIt team member, to jump into the creek this week (equipped with rubber boots and a sampling net).

A Tribute to Martin Reinhard: Conqueror of Environmental Chemistry and Mountains

March 27, 2012 | Stanford University

Few individuals have risen to the scientific heights of environmental chemistry as well as the physical heights of some of the world’s most challenging mountains.  But these two themes, and other personal traits in a unique career, were celebrated in a two-day Special Symposium at the American Chemical Society’s Annual Meeting in San Diego in recognition of Martin Reinhard’s contributions to aquatic environmental chemistry.

Rethinking Toilet to Tap

February 13, 2012 | UC-Berkeley

Did you catch the story on potable water reuse on the front of The New York Times on Friday?  When I checked on Friday afternoon, “As ‘Yuck Factor’ Subsides, Treated Wastewater Flows From Taps” was the fourth most e-mailed story.  For some reason, The Times listed it as the top recommended story for me (which tells you something about my reading habits).

Coming Face to Face with Engineering Challenges

January 19, 2012 | Stanford University

There’s an old joke about how you can tell if you’re talking to an introverted engineer or an extroverted engineer - the first looks at his own shoes, the other looks at yours. And as with many jokes, there’s an element of truth behind the humor.

Water's "Special" Economics

December 19, 2011 | Colorado School of Mines

Many people are familiar with the old Water and Diamonds Paradox: water, essential to life, costs almost nothing while diamonds, a superfluous luxury, cost millions of times that of water on an equivalent basis.  The apparent paradox dissolves a bit upon reflecting about the relative supply of the two resources.   If one person was sent outdoors to find water, and a second person sent out to find diamonds, there is no question as to who would succeed first.  (Note: I said these two were sent outdoors, not to the mall.)

Wastewater Treatment: It’s Not Rocket Science . . . Or Is It?

November 21, 2011 | Stanford University

When most people think of wastewater treatment, they probably don’t think of rocket science. Well, here at Stanford we are bringing rocket technology to wastewater treatment. Sounds crazy, right?

Where Do All the Science Majors Go?

November 10, 2011 | Stanford University

I am an Environmental Engineer:  BS, MS, and PhD.  I didn’t really think much about it; I chose the major in college because I was really interested in biology, chemistry, and the environment in high school.  And I just kept going with it.  This never seemed all that unusual or special to me, until I read Christopher Dew’s article “Why Science Majors Change Their Minds (It’s Just So Darn Hard)” in The New York Times last week.

The First Flush Blues

October 17, 2011 | UC Berkeley

It rained last week.  In most places this wouldn’t be a remarkable event, but it hasn’t rained in Berkeley for over half a year.  When I heard the sound of rain running across the roof, I knew that summer was really over and that we are moving from brown hillsides to fragrant mud on our way to the oddly premature spring that starts in February.  As required by the local building code, the rain that runs across my roof passes through a PVC pipe and into the street.  The runoff from my roof, along with that of the roofs of my neighbors and all of the water from the roads, driveways, and parking lots all flow through the streets on their way to the storm sewers that drain the city into San Francisco Bay.

Intergalactic Water Delivery?

October 10, 2011 | Stanford University

I stumbled upon a paper that was published in Nature last week, about researchers’ findings that the water in Earth’s oceans could have come from comets.  The research team discovered that the deuterium/hydrogen ratio in water on a particular comet called Hartley 2 is similar to that in our oceans.  Regardless of the exact percentage of water that arrived via comets or asteroids, I find it somewhat mind-boggling to consider the galactic “water infrastructure” that first brought water to the planet.

A Thirsty Golf Course Might Save Carmel's Salmon

September 26, 2011 | Monterey, CA

If you sit on the deck of Carmel’s Mission Ranch, Clint Eastwood’s restored hotel and restaurant on California’s Central Coast, you can see the Carmel River and the upper edge of the lagoon that attaches it to Monterey Bay. During much of the year, the Carmel River runs at a trickle because a dam and a series of upstream water users divert the water. Due to the low flow in the river, the Steelhead salmon waiting for the winter rains to connect the river to the ocean struggle to survive in the warm water. Perhaps Mr. Eastwood and the concerned residents of Carmel ponder the fate of the salmon as they discuss the water war and its legal twists and turns while enjoying the bucolic view from the deck. It’s too bad that they can’t see that help for the salmon is sitting just over the horizon.

A River Runs Through It

September 10, 2011 | A plane between St Louis and San Francisco

The Los Angeles River is one of the most-filmed waterways in Hollywood.  Its large, concrete-lined channels make perfect backdrops for action-thriller movies.  Untold high-speed car chases, dramatic airplane landings, and even sci-fi battles with gigantic mutant ants (Them) were filmed in those channels.  With its bare concrete abutments and hard-surface bottom, it doesn’t look anything like a river.

Weathering a Drought with Conservation . . .

September 6, 2011 | Stanford University

We’re all familiar with the proverb, “Necessity is the mother of invention.”  And whether you’re the type of person who believes inherently in the ability of technology to solve all the world’s problems, the type who believes technology causes all the world’s problems, or somewhere in between, you’ll likely agree that finding yourself with a scarcity of something that’s important to you will really get you thinking.  Especially when that something is as important as water.  Just ask a Texan.

Clean Water, Dirty Minds

August 29, 2011 | Colorado School of Mines

I had a driveway moment the other day, sitting in my car after I had arrived at my destination, listening to a story on NPR. The story was about water reuse, and began by describing how water engineers described public reaction to water reuse plans as irrational. Scientists like Brent Haddad at UC Santa Cruz, as well as environmental organizations, could provide overwhelming scientific evidence and logical justifications supporting intentional water reuse, but the public wasn’t buying it—they just found the concept fundamentally disgusting.

Water for Salmon, Water for Wine?

August 26, 2011 | Stanford University

While much of the U.S. east coast braces for too much water in the form of Hurricane Irene this weekend, constituents here in California are fighting over the typically low summer water flows in Sonoma County’s rivers and streams. This time, it’s wine versus salmon.

Can the Aliens Among Us Help Reinvent Urban Water?

August 23, 2011 | UC Berkeley

A few weeks ago Dick Luthy wrote a blog entry in which he compared the water rights tussle in Bakersfield to the alien invasion in the summer popcorn selling vehicle, Battle: Los Angeles.  I hate to admit that I took too many plane flights this summer and after giving up on my work, Sudoko puzzle, and book I was forced to watch this movie (without popcorn).  Aside from some special effects that don’t look like much on a tiny screen without 3-D glasses, the take home message for me was that the aliens are coming and when they get here they’ll pass up Manhattan, Tokyo and Paris for the opportunity to stick a long tube into the sewer and steal L.A.’s water.

Recycled Water: The Uphill Education Battle

August 16, 2011 | Colorado School of Mines

My infant son is only six months old, but my wife and I already have a very large collection of books for him to (eventually) read.  One that I picked up the other day is Richard Scarry’s What Do People Do All Day?, which I am told by some labor economists is a surprisingly good representation of our workforce . . .

Die Hard: Bay Area Style

August 7, 2011 | Stanford University

The thriller-action movie Die Hard With a Vengeance was the third movie in the Die Hard series staring Bruce Willis, who plays a police officer trying to catch would-be terrorists. The plot takes a twist when Bruce Willis discovers that threats of explosions are diversions while thieves raid the Federal Reserve Bank of New York. The thieves load up $100 billion of gold bullion in dump trucks and then make their getaway. But something happens. As the heavily loaded dump trucks escape lower Manhattan they suddenly disappear. How can that happen? It was possible because the thieves knew something about urban water infrastructure. Really!

Battle: Bakersfield (?)

July 27, 2011 | Stanford University

The recent action/thriller movie, Battle: Los Angeles, is about aliens who descend off the coast of California and begin an attack on the city of Santa Monica. In truth, this movie is only for the most ardent action junkies and the reviews aren’t very good. Without spoiling the plot, the Marines take a stand on Lincoln Boulevard and save the day. The movie is murky — both in story and filming. One brief scene explains amid a bunch of distracting special effects why the aliens came to Earth and what they want. Apparently they’re after our water! Yes, amid all the other water wars occurring in the west, now we have to deal with aliens as well.

Echoes of Dan Okun

July 26, 2011 | UC Berkeley

A lot of you probably never heard of Dan Okun. I never met him but I have read several of his papers and have met a bunch of prominent people who were inspired by his vision of how urban water infrastructure could be reinvented using dual distribution systems and water conservation. But that‘s a discussion for another day.

Open for Business

July 20, 2011 | ERC Headquarters

It‘s finally official. NSF sent us notification that our Engineering Research Center will be funded starting on August 1. After an 18-month period consisting of a pre-proposal, proposal, site visit, reverse site visit, three research planning meetings and a seemingly unending progression of conference calls we are ready to start a journey into uncharted territory.

Opportunities in the Urban Water-Energy Nexus

July 13, 2011 | Singapore Water Leaders Summit

The term “water-energy nexus” is an overused way of saying that it takes energy to get water where you need it and you have to get water to the place where you need to make energy. Many pundits and researchers have offered their analyses of the connection between energy, water and food production but until yesterday I had heard little compelling about water and energy use in cities.

2011 AEESP Education and Research Conference

July 12, 2011 | Tampa

The gathering at the University of South Florida in Tampa, FL, is the largest-attended biannual conference of the Association of Environmental Engineering and Science Professors [AEESP]. We are here along with John McCray and Kara Nelson, representing ERC faculty at the meeting. Described by some attendees as the “sweatiest AEESP conference ever,” the discussions over the past two days resonate well with the themes of the ERC, with conference sessions on urban water infrastructure systems and alternative water strategies.

Necessity is the Mother of Reinvention

July 5, 2011 | From the Singapore Water Leaders Summit

It's only fitting that the first entry in this blog should come from Singapore. After all, aside from their dislike of chewing gum and the overall tidiness of the place, this island nation is probably best known for water reinvention.
